In case anyone wasn't aware, nearly all space photos that you've ever seen have had their colours tweaked. It's standard practice in space photography. Nebulae and galaxies and planets aren't as colourful as they appear in photos. They do it either to make the features more obvious for study, or just to make them pop more to drum up interest in space exploration. Nothing wrong with it, just be aware that what you see isn't reality but an interpretation.
